Gabriel Castillo was 23 when he was shot and killed at Floyd Gwin Park in Odessa, Texas, on July 29, 2014. Born March 17, 1991, in Lubbock and known as Blu, he moved to Odessa in 2005, attended Odessa High School, and worked for Pro Petro Drilling on Rig 205. Family and friends remembered his love of cars, music, and sports.

The investigation resulted in multiple arrests. Jorge Leyva, then 16, was arrested and later tried as an adult for the murder. Nineteen-year-old Cesar Ulate was charged with capital murder and admitted being at the scene. Christina Renteria was arrested for tampering with evidence and making a false report after allegedly misleading police about the location of an SUV tied to the shooting; her son Adolfo Renteria, 20, was identified as the vehicle’s driver and was at large during the probe.

Does anyone who knew Gabriel or was in Odessa that night have information that could help fill gaps in the case?
